Multi-Component Metal Oxide Nanoneedles as Pseudocapacitor Electrodes

Summary

To solve these issues, Purdue University researchers have developed a multicomponent NixCoyMn1-x-y oxide with a homogenous structure for use in high performance supercapacitor applications. This arrangement exhibits a three-fold higher capacitance than that of NiCo2O4, has excellent long-term stability, and has low internal resistance. This development is advantageous due to the unique homogenous structure of the metal oxide with uniform distributions of nickel, cobalt, and manganese metals; enhanced oxidation state; and provides synergy with the different metal components, which can lead to a wide variety of applications in the supercapacitor industry in competition with batteries and in future designs of novel electrode materials.
